LOCK.

srnorrrca'rron forming part of Letters Patent No. 649,706, dated May 1 5, 1900.

Application filed January 2'7, 1900. Serial No. 2,960. (No model.)

To aZZ whom it may concern.-

Be it known that I, BYRON PHELPs, a citizen of the United States, residing at Seattle, county of King, State of Washington, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description.

My invention relates to improvements in door-locks; and my object is to improve the construction of the same, particularly with reference to a means for locking one or both of the knob-spindles.

In the preferred embodiment of my invention shown in the drawings, Figure 1 represents a plan view of a lock embodying my invention, parts being shown in section. Fig. 2 is a section on the line Y Y, Fig. 1, looking from left to right. Fig. 3 is a similar view to Fig. 2, with the parts in slightly-different position. Fig. a is a side View of the thumb-piece detached. Fig. 5 is a detailed view of the end of the bearing and spindle with the locking-pin in its locking position. Fig. 6 is a section on the line X X, Fig. 1, looking in the direction of the arrow. Fig. 7 is a detailed view of the middle part of the spindle.

In'the above preferred embodiment I have shown my invention as applied to a lock which is adapted to be inserted in the notch in the stile of a door and of the general construction claimed in my Patent No. 626,340, dated June 6, 1899.

In the embodiment shown in the drawings, A is the frame for the working parts of the lock, which, as above stated, is adapted for insertion in the notch in the stile of a door and of course is stationary relatively to the moving parts of the lock mechanism. B and O are spindle-bearings, in this embodiment preferably integral with the frame and extending transversely from each side thereof. As these spindle-bearings are in this embodiment integral with the frame, they also are stationary relative to the moving parts of the locking mechanism. Within these spindlebearings is a rotatable spindle D, preferably extending through both spindle-bearings and carrying on each end thereof a handle, preferably knobs I) I). The inner ends of these spindle-bearings B and O are separated by the opening A, butare preferably connected togetherby the bridges a ct. The middle part of the spindle D has an opening through it, preferably of the shape shown in Fig. 7, and within this opening are two roll-backs, one of which, E, is located in and fits the small slot E in the spindle and the other one, E is freely movable in the larger part E of the opening.

F is a yoke embracing the spindle with its two legs and having an inturned foot F on each leg, which feet lie behind the roll-backs, as shown in Fig. 1.

G is a latch-bolt or head pivoted at g,to which the forward end of the yoke F is attached, and f is a spring to normally keep the yoke and latch-bolt in the position shown in Fig. 1.

It is obvious that when the spindle is rotated the roll-back E will throw back the yoke and also the latch-bolt. The part shown in dotted lines at the left of Fig. 1 constitutes a part of the mechanism whereby the roll-back E may be rotated and the latch thrown back by a key inserted in the knob D even when the spindle is locked. This mechanism,which has been heretofore described, is claimed and more fully described in my former patent, No. 631,433, dated August 22, 1899.

To hold the spindle D immovable, I have provided a locking portion, in this embodiment a spring-pressed pin l-I, carried by the spindle, preferably in an opening in the same, which in this embodiment is formed by the hole d, extending into the interior of the hollow spindle and registering with a hole in a block d, inserted in said spindle. The relatively-stationary part, which in this embodiment is the right-hand spindle-bearing B, has an aperture b, preferably formed, as shown in Fig. 5, in the end of said bearing and partially registering with said hole 01 in the spindie, so that when the hole (Z in the spindle registers therewith the coiled spring will press the locking-pin outward radially-that is, away from the axis of the spindle, asshown in Fig. 1into engagement with said stationary spindle-bearing, thus locking the spindle against rotation. As the end of the spindle bearing in this embodiment does not cover the hole d entirely, the pin when projecting outward, as in Figs. 1 and 5, will be partly ere posed outside of the spindle. In order to move the pin inward, so as to unlock the spindle,I have provided a movable and preferablyrotatable finger-piece located outside of said spindle and between the handle, in this embodiment the knob and the latch mechanism. This finger-piece is preferably in the form of a cup-shaped ring K, provided with an inter-' nal shoulder K, as seen in Figs. 1, 2, and 3, which shoulder preferably rests against the end of the spindle-bearing, as shown in Fig. 1, and may be held in place by the handle or knob D. The thickened portion of the finger-piece formed by the shoulder K is cut away, as seen in Figs. 2 and 3, to form camfaces K hen the finger-piece is in the position shown in Figs. 1 and 2, the spindle is locked; but when said finger-piece is rotated one-quarter of a revolution the cam-face K rides upon the exposed portion of the pin and presses the same inward until it passes out of engagement with the stationary part or spindle-bearing. The spindle can then be turned. To prevent the displacement of the fingerpiece with respect to the pin when the spindle is rotated, I have provided slight depressions K K in the finger-piece, into which the pin snaps to lock the finger-piece in position and yet keep the pin depressed far enough, as seen in Fig. 3, so that the spindle will remain unlocked. By the foregoing arrangement I have provided a device to lock the spindle, but which in this embodiment will allow the latch-bolt G to be pushed back.

In Fig. 6 I have shown a thumb-nut M engaging with a rotatable dog m, which can be thrown forward, as shown in dotted lines, into engagement with the latch-bolt G to positively lock the same from movement.

It will be obvious that very many changes may be made in the construction herein disclosed without departing from the spirit of my invention, and I therefore do not wish to limit myself to the particular embodiment herein shown and described.

In a lock in combination,-latching mechanism, a relatively-stationary part, a spindle rotatable in saidstationary part and connected with said latching mechanism to operate the same, a handle on said spindle, a locking portion carried by said spindle and movable radially outward into engagement with said stationary part to lock said spindle from rotation, and a movable finger-piece located outside said spindle and between said handle and latch mechanism and connected with said locking portion to move the same.
